Power management integrated circuits (PMICs) are a key component in many electronics. One type of PMIC, motor drivers, controllers, is particularly useful for controlling electrical motors. The ATA6824-MFQW is one such motor driver, controller. It is designed for use in brushless DC motor (BLDC) and three-phase sinusoidal BLDC motor control.

The ATA6824-MFQW is equipped with an integrated three-phase 180-degree sinusoidal current excitation algorithm layer. It uses a three-phase 120-degree voltage output architecture that manages the tradeoff between performance and efficiency. This motor controller also comes with advanced functions including torque degradation, speed control, and current phase shift control.

This motor controller efficiently increases the motor by controlling the motor current and voltage via PWM modulation in three-phase 180-degrees sinusoid. Despite its high degree of efficiency and accuracy, the ATA6824-MFQW is surprisingly compact and cost-effective. It requires few external components, reducing design complexity and cost. Its operating voltage range is 6.0 V to 28 V.

The ATA6824-MFQW supports full digital control using a single-wire interface for low speed control, such as fan control and simple sinusoidal control. For more complex brushless motors, the motor controller is connected to a microcontroller, which provides full digital control. It comes with built-in safety features such as short circuit protection, over-temperature protection and under-voltage lockout.

The ATA6824-MFQW is used in a variety of applications including automotive, industrial, and consumer products. In automotive applications, it is used for power door lock/ actuator control, as well as window wiper control and HVAC systems. In industrial applications, the motor controller is used for controlling brushless fans and pumps, as well as robotic arm motion control.

The ATA6824-MFQW draws on advancements in digital technology to provide improved accuracy and efficiency for BLDC motor control. Its advanced features, combined with its convenient size and low cost make it an ideal choice for motor control applications.
